<span style="color: rgb(0, 0, 0);"><span class="hover:entity-accent entity-underline inline cursor-pointer align-baseline"><span class="whitespace-normal">OpenSSL</span></span> is a widely used open-source software library designed to provide secure communication over computer networks through encryption and cryptographic techniques. It implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, which help protect sensitive information exchanged between clients and servers. In addition to enabling secure connections, OpenSSL offers a variety of cryptographic functions, including data encryption, decryption, digital signatures, and certificate management. Due to its reliability, flexibility, and broad platform support, OpenSSL has become an essential component in many web servers, applications, and operating systems worldwide.</span>
